Last year I finally got a 4K monitor. I still have two 13-year-old 27" Apple Thunderbolt displays to the left and right. But my main monitor is a 32" Samsung 4K monitor11 SAMSUNG ViewFinity S7 LS32D700EAUXXU 4K Ultra HD 32" VA LED Monitor - Black. So when I'm building/designing things like this blog I'm looking at a 4K monitor. And the first thing I realised when I started using 4K is just how tiny things like text look. But plenty of people are still on HD monitors. So it's always a bit of a shock how big this blog looks when I view it on my office’s HD monitor. It's tough – what do you design for? The new (4K)? Or the old (HD)?#
